What it does
Kb Severity Mapping is an agent skill from Community-Access/accessibility-agents. Reference data, not a reviewer. Canonical severity level definitions and cross-domain mapping for web, document, and markdown audits. Score impact ranges, WCAG conformance alignment, and cross-format normalization.
Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Frontend & Design, covering Accessibility and Database schema design. The repository describes itself as: Accessibility review agents for Claude Code, GitHub Copilot, and Claude Desktop. Eleven specialists that enforce WCAG 2.2 AA compliance so AI coding tools stop generating… The licence is MIT.
When your agent uses it
- Tasks that involve Accessibility
- Tasks that involve Database schema design
Example prompts
- “/kb-severity-mapping”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Map each finding to the canonical severity level using the table above.
- Apply the score impact from the canonical level, not from the domain-specific tool's internal scoring.
- For aggregated scores (portfolio or project level), compute each page/file score independently, then average.
- Do not double-count a finding that appears in both an axe-core scan and a Playwright behavioral scan -- deduplicate by rule ID and element…
What it can do on your machine
Read from SKILL.md and the folder at commit decf6ba. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Kb Severity Mapping loads about 908 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 423 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Severity Mapping
Canonical severity definitions shared across web, document, and markdown audit domains.
Canonical Severity Levels
Each level, with its definition, WCAG conformance and score impact.
| Level | Definition | WCAG Conformance | Score Impact |
|---|---|---|---|
| Critical | Blocks access entirely for one or more user groups. No workaround exists. | Fails Level A | -15 to -22 points |
| Serious | Severely impairs access; a workaround may exist but is unreasonable. | Fails Level A or AA | -5 to -10 points |
| Moderate | Causes friction or confusion; most users can still complete the task. | Fails Level AA (advisory) | -2 to -4 points |
| Minor | Polish issue; no meaningful barrier for most users. | Technique deviation | -1 point |
Cross-Domain Equivalents
Each canonical level, with its web (axe-core or playwright), document (office or PDF) and markdown.
| Canonical Level | Web (axe-core / Playwright) | Document (Office/PDF) | Markdown |
|---|---|---|---|
| Critical | critical (axe-core) | Missing document title; untagged PDF; missing heading structure | Broken anchor link leading to dead navigation |
| Serious | serious (axe-core) | Missing alt text on informational image; table has no headers | Ambiguous link text (e.g., "click here"); missing alt text on image |
| Moderate | moderate (axe-core) | Merged table cells; color-only data encoding | Skipped heading level; missing table caption |
| Minor | minor (axe-core) | Decorative image with non-empty alt; redundant bookmark | Emoji in heading; em-dash used as list separator |
Score Impact Rules
Score impacts listed above are additive per finding. When the same issue recurs across many elements:
- First occurrence — full deduction
- Same issue type, same page/file — no additional deduction (already counted once per issue rule)
- Same issue type, different page/file — full deduction applies again to the new page/file score

Conversion Rules (Normalizing Cross-Domain Reports)
When generating a unified report that combines web, document, and markdown findings:
- Map each finding to the canonical severity level using the table above.
- Apply the score impact from the canonical level, not from the domain-specific tool's internal scoring.
- For aggregated scores (portfolio or project level), compute each page/file score independently, then average.
- Do not double-count a finding that appears in both an axe-core scan and a Playwright behavioral scan -- deduplicate by rule ID and element location.
Confidence Modifier (Web Domain)
For web audits, confidence level modifies the base deduction:
| Confidence | Multiplier | Source Signals |
|---|---|---|
| Confirmed | 1.2x | axe-core + agent code review + Playwright behavioral test |
| High (two sources) | 1.0x | Any two of the three sources above |
| High (one source) | 1.0x (reduced base) | Single automated tool, high rule reliability |
| Medium | 0.7x | Single source, medium rule reliability |
| Low | 0.3x | Single source, low rule reliability or heuristic |
Document and markdown audits do not use confidence multipliers -- they use the base score impact only.
